Hi, a friend of mine just shot some scenes on which the director asked him to switch from std 4:3 aspect ratio to 16:9. when he switched, the image on monitor looked out of focus ( like when back focus is moved from its proper position ) he did grab focus again, adjusted back focus, image was the same, what's curious is that in the view finder, it looked ok ( in focus ) and in the monitor out of focus, he then checked previous footage on playback, and it looked ok, so the problem was not the monitor or video cable, anyone has any clue on this? can be the swtich from 4:3 to 16:9 make this happen? should some parameter in the menu be taken in consideration for adjustment when doing this? Thanks for any clues.

Indeed, Mr Mullen, monitor was 16:9 switchable, Lens on aprox of 50mm on the zoom and a stop about F 4.0 . Playback looked ok sharp on focus, image on viewfinder also did appear in sharp focus, when switched to 16:9 aspect, image on monitor was soft focus, but looked sharp on VF, also playback looked ok from some previous scenes.
Thanks so much indeed.

I can't understand what the difference would be between a 16x9 signal coming live from camera into the monitor versus a recorded 16x9 signal coming down the same cable, and why the live signal would look out-of-focus on the same monitor. Sounds like a maintenence problem with the camera.

Hi,

There are two sets of many adjustments for the 4:3 and 16:9 modes on many monitors; try playing back the wide material in 4:3 mode and check if it's in focus there.
